Based on this image, you can see a faint "1" between the 9s. I've seen enough 1909 and 1919 LWCs to know the difference.
You are entitled to your opinion. an in-hand view is better than a 100 pictures so if it's a keeper keep it... Live long and proper! Good luck
Mostly due to the spacing between the second and fourth digits in the date. They are too narrow for a zero.
Looks like a spender to me. One of the professors at the university I worked for believed he could see micro-graffiti on ancient coins. He also collected U.S. coins. Perhaps he thought he could see a VDB on the reverse of 1919-S cents!
The maps are drawn in TurboCad. All my maps are saved in a library of cad drawings. I import the target image into the TurboCad workspace and overlay the map on top of the image. Use relative coordinates to generally size and orient the map on top of the image.
Heck I am just a dumb farmer - you probably could unlock more power out of the Cad software than I. I worked as a surveyor for a civil engineer for several years way back when in college getting my accounting degree. When I see an image of a coin - I don't see a coin anymore. I see an aerial map of unknown scale.
